There are other thread[s] on Julia and real-time, I'll not repeat here. You are ok with Julia for real-time work? Julia strictly isn't real-time, you just have to be careful. I'm not looking into your embedding/GC issues as I'm not too familiar with. Seems to me embedding doesn't fundamentally change that the GC isn't real-time. And real-time isn't strictly about the performance. > However, for this usage I need to retain Julia state variables across c++ > function calls, so the stack based JL_GC_PUSH() and JL_GC_POP() are not > sufficient. > When I injected some jl_gc_collect() calls for testing purposes, to > simulate having multiple Julia scripts running (from the same thread), I > got crashes, which I was able to fix using e.g. jl_gc_preserve(mMyState); > and appropriate matching jl_gc_unpreserve() calls. > > I see these functions have been removed from the latest Julia version. > > Is there an alternative that allows Julia values to be retained in a C++ > app across gc calls? > -- Palli.
